DEFINITION

Classification: 523/502

Composition contains water-in-oil or oil-in-water mixture:

(under subclass 501) Subject matter wherein the composition contains or is prepared as an water-in-oil or oil-in-water emulsion, i.e., a fluid in which one liquid forms minute droplets suspended in the other liquid.

(1) Note. A polymer suspension product prepared in part from an emulsified ingredient will not be considered as an emulsion but as a suspension, i.e., finely divided particles floating in a liquid and kept in this state by Brownian movement.
